3-2. Advanced BIOS Features

Virus Warning:
When set to [Enabled], the BIOS will monitor the boot sector and partition table of the hard disk drive. If
there is any attempt of writing to the boot sector or partition table of the hard disk drive, the BIOS will
halt the system and an error message will appear.
CPU L1 & L2 Cache:
This item is used to enable or to disable the CPU level 1 cache. When the cache is set to Disabled, it is
much slower, so the default setting for this item is Enabled since it will speed up memory access. Some
old and very poorly written programs will make the computer malfunction or crash if the system speed is
too high. In this case, you should disable this feature. The default setting is Enabled.
Quick Power On Self Test:
When set to [Enabled], this item speeds up the Power On Self Test (POST) after powering on the system.
The BIOS shorten or skip some check during the POST.
First Boot Device / Second Boot Device / Third Boot Device / Boot Other Device:
Select the drive to boot first, second and third in the [First Boot Device], [Second Boot Device], and
[Third Boot Device] items respectively. The BIOS will boot the operating system according to the
sequence of the drive selected. Set [Boot Other Device] to [Enabled] if you wish to boot from another
device other than these three items.
Swap Floppy Drive:
When set to [Enabled], and the system is booting from the floppy drive, the system will boot from drive B
instead of the regular drive A. There must be two floppy drives connected in the system to use this
function.
Boot Up Floppy Seek:
When set to [Enabled], the BIOS will check whether the floppy disk drive is installed or not.
